How Do I Install the MLNX Driver?

Install the MLNX driver on HCE OS 2.0 (including x86 and Arm).

Constraints

  • The kernel of HCE OS 2.0 is Linux 5.10 or later.
  • The CX6 NIC driver version is 23.10-1.1.9.0-LTS or later.

Prerequisites

HCE OS 2.0 with kernel 5.10 or later has been installed.

Installing the MLNX Driver for the x86 Architecture

  1. Download the CX6 NIC driver installation package MLNX_OFED_LINUX-23.10-1.1.9.0-openeuler22.03-x86_64.tgz.
  2. Decompress the package and go to the working directory.

    tar -xf MLNX_OFED_LINUX-23.10-1.1.9.0-openeuler22.03-x86_64.tgz

    cd MLNX_OFED_LINUX-23.10-1.1.9.0-openeuler22.03-x86_64

  3. Install the CX6 NIC driver.

    ./mlnxofedinstall --basic --without-depcheck --distro OPENEULER22.03 --force --kernel 5.10.0-60.18.0.50.oe2203.x86_64 --kernel-sources /lib/modules/$(uname -r)/build

    5.10.0-60.18.0.50.oe2203.x86_64 is the kernel version when the official MLNX_OFED package is compiled.

  4. Create a link.

    ln -s /lib/modules/5.10.0-60.18.0.50.oe2203.x86_64/extra/mlnx-ofa_kernel /lib/modules/$(uname -r)/weak-updates/

    ln -s /lib/modules/5.10.0-60.18.0.50.oe2203.x86_64/extra/kernel-mft /lib/modules/$(uname -r)/weak-updates/

    depmod -a

  5. Run reboot to restart the OS.
  6. Run the /etc/init.d/openibd status command to check the driver installation result.

    If the following information is displayed, the driver is installed:

Installing the MLNX Driver for the Arm Architecture

  1. Download the CX6 NIC driver installation package MLNX_OFED_LINUX-23.10-1.1.9.0-openeuler22.03-aarch64.tgz.
  2. Decompress the package and go to the working directory.

    tar -xf MLNX_OFED_LINUX-23.10-1.1.9.0-openeuler22.03-aarch64.tgz

    cd MLNX_OFED_LINUX-23.10-1.1.9.0-openeuler22.03-aarch64

  3. Install the CX6 NIC driver.

    ./mlnxofedinstall --basic --without-depcheck --distro OPENEULER22.03 --force --kernel 5.10.0-60.18.0.50.oe2203.aarch64 --kernel-sources /lib/modules/$(uname -r)/build

    5.10.0-60.18.0.50.oe2203.aarch64 is the kernel version when the official MLNX_OFED package is compiled.

  4. Create a link.

    ln -s /lib/modules/5.10.0-60.18.0.50.oe2203.aarch64/extra/mlnx-ofa_kernel /lib/modules/$(uname -r)/weak-updates/

    ln -s /lib/modules/5.10.0-60.18.0.50.oe2203.aarch64/extra/kernel-mft /lib/modules/$(uname -r)/weak-updates/
